Application led March 31, 19.133. Serial No. 75?,812.

To all who??? it may concern.' I

Be it known that WILLIAM l). Fon` SYTH, a citizen of the United States, residing .at Youngstown, inthe county of Mahoning and State of Ohio, have' invented new and useful lmprovements in Removable Assembled Draft-Gears, of which the following is a specification.

My inven'i'cn relates to improvements in draft gears for use on railway cars.

The principal objects of my invention are, among other things, to provide a draft gear `whoseparts can'be readily assembled,

and when assembled, separated from oneanother without a' complete distribution of the several .devices entering into any particular partJ of it, and at the saine tirnebe 'applied .to 'cars when the parts thereof are assembled with relation to one another; also to provide a draft gear wherein the parts that are subject to tension when said gears are in operation on the cars, are constructed of rolled metal sections, and the parts that are subject to compression under like circumstances are .constructed of cast metal.

" invention vconsists of the removablev assembled draft gear hereinafter described and claimed Like figures of reference' refer to `like parts throughout.

Figure 1 represents a vertical tip plan View of my improved draft gear as t 'e same would appear mounted between the draft sills of a c'ar, the'said draft sills being partly in section. Fig. 2 is a vertical longitudinal section of Fig. lyon section line 1 -1. Fig.

- 3 is a vertical longitudinal section similar to'Fig. 2, showing a modified construction.

In Fig. 1; l, 1, are draft sills having holes 2, 2, pierced therein. 3, 3, are bars bolted to the bottom flanges of 1, 1, by tap bolts 4, 4, which support the draft gear between the sills when mounted on the car. 5, 5, 5, 5,

are cleats fixed to the web of sills 1, at.

suitabledistances, as shown in the drawings, preferably by riveting the same thereto. In Figs. 1 and 2, 6 is a draw bar yoke formed from a single piece of rolled metal, preferably steel, having shoulders at 7 and 8. 9 is a casting, having flanges 10, 10, and compartments 11, 11, 11, which are formed between the ends and sides of 9 by abutments 12, 12. Casting 9 is countersunk at 13, and has ahole, at 14, abutments 12,

have holes 15, 15. 16 is a bar or a pipe,

(shown in the drawings as a.pipe)- insertible in the casting and its abutments as shown in Figs. 2 and 3. 17 is a part of a draw bar of the ordinary construction, with the coupler end not shown, having a lhole 18 and a shoulder 19. 20 is a pin adapted to be passed through hole 18 of draw bar 17, having Cotter pins .21, A21. 22 is-a rec tangnlar link or collar of sufficient size 'to pass over the front'ends of yoke 6. 24, 24, 24, 24, 24,124, `are follower plates or spring seat plates, having holes 25 for the passage j of bar or pipe 16. 26, 26, 26, are spiraLl springs adapted to Vabut upon the follower plates 24, and to be mounted upon pipe or bar 16. Fol-lower plates 24 abut at each of their edges against cleats 5, fastened to webs .which is heldin place by cotter pin 31; rEhe lfrent ends ,of said draw bar yoke 2'?, Fig.

3, are connected by a collar 22, and draw bar 1f? is inserted in .the same method or manner as draw bar -17 of Figs. 1 and Y1n assembiing the parts of the draft gear 4 shown in Figs. 1" and .2 of the drawings,

follower plates and springs are mounted in ipe 16 and are placed in the compartments of the vblock or spring case, where they ,are Centered by putting the. ,bar or pip" 16 through the holes in the' rear end o block and its several abutments ano the socket at its front end. When the yoi're is composed of a single rolled metal piece, its front ends are sprung suiiiciently to permit them to pass between the flanges of the block, so that the intermediate shoulders of the yoke abut the front end of the block. The fianges of the block prevent the yoke from slipping off the block.l The collar is passed over the rear end of the draw bar. The rear end of the draw bar is then placed between the front end of the block and the terminal shoulders of the yoke. Then the collar is passed back over the ends of the yoke and fastened in place by a pin passing through the perforation of the draw bar. The assembled draft gear is now a unit which can be `liandled, transported, tafen,

lill@ o and -put oncars without disturbing its dierent parts in their relations to one another until intentionally separated. rllhe removing or fixing of the support bars of theY lower flanges of the draft sills of the car is -all that is necessary to-be done to permit the assembled draft gear to be put on or taken'of the car on which it is to be used. Where the yoke is constructed as shown in Fig. 3, the two yoke side bars are assembled in a manner that is obvious from their shape and construction. When the two piece yoke bar is thus assembled' and used, the assembling of the rest of draft gear is substantially the same as in the case where the yoke is constructed as shown in Figs. l gud 2.

While li have shown butv asingle spiral spring in each compartment of the block in the drawings, one or more of said springs may be in each compartment of the block without departing from the spirit of my in.`

vention.

What li claim as my invention is:

1. A draft gear comprising a spring case having compartments therein,a draw bar yoke mounted' on saidspring case and having shoulders abutting the front end of said spring case, the end portions of said yoke extending beyondl -the front endof said spring case, the ends of said end portions of said yoke being inturned'toward each other, a draw bar mounted'between said 'end portions and having' shoulders engaging said inturned ends, said draw barbeing in contact with the front end of said 'spring case, and detachable means for holding said yoke in place on said draw'bar. y

2. A draft gear comprisin yoke having the ends thereof inturned toward each other, a spring case removably mounted in said yoke2 a draw bar mounted between the end portions of said yoke and a draw barv Liedes@ end portions of said yoke and retaining said yoke in position on said draw bar, and a removable pin passing through said draw bar and holding'said collar in place.

3. lin a dra-ft gear, a draw bar yoke, a draw bar removably secured to said yoke, and la spring case removably mounted in said yoke and bearing against said draw bar and said yoke, said spring case havingtwo flanges projecting from each of two opposite longitudinal faces thereof, said yoke lying between said flanges. y v

4. lin a draft gear, a draw bar yoke, a draw bar removably secured to the ends of said yoke, a spring case removably `mounted within said yoke and bearing against said draw bar, said spring case having compartments therein, a pair of follower plates in .each of said compartments, a spring between each pair of said follower plates, and a removable. rod extending longitudinally of said spring case through said follower plates and said springs.

5. lin a draft gear, a draw bar yoke, a spring case-removablymounted within said yoke, said spring case having compartments therein, a pair of follower plates and a spring in leach of said compartments, and va removable rod extending longitudinally of said spring case through said .follower plates and said springs.

lin witness whereof l my hand in the presence of two subscribing witnesses. f
